If #SCOTUS devises a test: Do they apply it themselves? (Doubtful) Or do they return the case to District Court Judge Tanya #Chutkan & instruct her to apply it? (More likely) If the justices apply the test themselves & allow some of the charges against #Trump to stand, the case could proceed. But if the court asks Chutkan to apply a test & she finds Trump is not #immune from prosecution, then Trump would undoubtedly appeal which would further delay a trial.
